To all whom z'tnmy concern:

Be it known that I, FRANK MoLAneHLIN, of the city of Toronto; in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Fountain Lather-Brushes, of which the following is aspecification'.

My invention relates to improvements 1n fountain lather brushes, the bristles of which are to be supplied with fluid, semifluid or plastic substance and the object ofthe invention is to devise means for feeding a fluid, semi-fluid or plastic substance from a container forming a reservoir into the bristles of a brush at a point in proximity to the free ends of the bristles, the discharge opening being located normally at the base of the bristles and it consists essentially of.

the following arrangement and construction of parts as hereinafter more particu larly explained. 77

Figure 1.is a side elevation of a lather brush to which my invention is particularly 1 indicates the container or reservoir in which the fluid or semi-fluidsuch as liquid soap or plast1c soap is contained when the device is used in connection with ashavi-ng brush. The container 1 has a spiral thread 2 formed in the cylindrical wall, thereof for a purpose which will hereinafter appear. The lower end of the container 1 is flared outward at 3 so as to form an annular hollow head 4, the center of the bottom being raised upward at 5 and provided at its center with a conical protuberance 6 surrounded by a depression 7 forming an annular groove around the protuberance 6. 10 indicates a cap provided with a central circular orifice 11 and a depending flange 12 provided with a thread corresponding to the thread 2 with which it engages. The cap 10 is provided with a neck 13 having an annular constricted portion 13* extending around the orifice 11. The lower portion of the tube 14 is hexagonal in cross section and the upper portion cylindrical on the exterior. The

1 into proximity to the lower end thereof, a

slight clearance being left at such flower end between its interior edge and the protuberance 6 and between its lower end and the base of the groove 7. Although I have dedescribed the tube 14 as hexagonal, it will of course be understood that any'shape might be employed which will impart a direct longitudinal andguided movement to tube 14 extends vertically through the orithe 11- and centrally through the container the .piston'41 hereinafter described. 15 indrcates perforations formed in the wall of the tube 14 in proximity to its lower end. 16 indicates a collar which surrounds the tube '14 intermediately of its length and is lQCated within the neck 13 of the container 1. The collar 16 fits freely around the cylin- 'd-r-ical portion of the tube 14 and its outer periphery is cylindrical so as to fit within the neck 13 in which it is secured. The space {between the collar 16 and the constricted portion ofthe neck 13 is filled with suitable packing 17." 18 indicates a collar which isv secured to the tube 14 and is located above the collar 7 16. 19 indicates a com- .pression springextending between the collar 16 and the collar 18. The tube 14 is provided with an extension sleeve 14 secured thereto having a closed upper end and openings in proximity to such closed end. 24

indicates a sleeve which surrounds the extension 14 and is provided with a shoulder 29, bearing against the lower end of such extension 14*. The sleeve 24 normally forms a closure for the openings 21. The lower end of the sleeve 24 is provided with a brush base receiving cup 26, the wall 27. of which is provided with a threaded portion 28.

It will be noted particularly on referring to Fig. 3 that the exterior of the sleeve 24 is Y cylindrical. 130 "indicates a lather brush provided with a metal base 31 fitting within the cup 26 and provided'with athread'33 engaging the thread 28 of the cup 26. The base 31 is provided with a. cylindrical sleeve 32 fitting around the sleeve 24. The brush and brush base can be easily removed by unscrewing such brush base from the threaded portion of the cup 26. 34 indicates a compression s ring extending between the collar 18 and t. e opposing face of the cup 26. The

spring :34 normally forces the cup 26 upward carrying the annular shoulder 29aga1nst the lower end of the sleeve extension 14*. e1 indicates a piston located within the con tainer 1, and provided with a central hexagonal orifice fitting the tube 14:. The piston 41 is formed by an upper metal plate 12 and a lower metal plate 43. The metal plate 43 is provided with a depending annular flange 44 which also has a thread 45 rolled therein which engages with the thread 2 of the container 1. 416 indicates a packing of leather or other suitable material located between plates 42 and '13, such plates being volved in my invention I will secured together by rivets 47 extending through the plates and packing.

Having described the principal parts inbricfiy describe the operation of the same.

} The manipulator of the brush when he desires to supply such brush with soap grips the brushbaseholder formed by the cup 26 in one hand andthe beaded portion 41 of the container in the other hand. He then forces the partstogether compressing the spring 34. By this means the brush base together I 30 upward longitudinally of the brush bristles wvith the sleeve 24 and the cup 26 is slid downward upon the tube 14 and simultato a point in proximity to the free ends of the bristles. The manipulator of the brush while holding the brush holder 26 and collar 18 secured to the tube 14 stationary with one 1 hand, turns the container 1 with the other hand. As'the piston 41 is held from movement by reason of the sides of its central hexagonal orifice binding upon the hexagonal tube 1 1, the reservoir is'carried longitui 45 compressing the spring 19.

dinallyby the tread 2 engaging the thread As soon as f thereservoir is manually released the spring 19 carries it downward together with the piston 41 which slides freely down the tube l4 to a new position inwhich it again binds on the tube at the next operation. of the reservoir. By this means the soap is forced perforations 15, the lower end of the tube of course being forced against the base of the groove 7 as the compressionspl'ing openings 21 onto the bristles of the brush. From this description it will be seen that I have devised a very simple means whereby soap in either fluid semi-fluid or plastic form v may be fed into the bristles of a brush in proximity to the free ends" of the bristles.

It may be pointedout that it is of great adv antageto discharge the soap onto the A free ends of the bristles as such bristles are spread apart at their free ends and not packed together as at their base allowing of the free passage of air into and through this portion of the brush so as to combine more readily with the'soap to turn it intolather.

' What I claim'as my invention is:

to and away from the free ends of the bristles of the brush. 1

' In a brush, adischarge tube adapted to be connected to a reservoir, a brush head having an unobstructed orifice extendingl through the base thereof and in which the discharge end of the tube slidably fits whereby such discharge end passes out of the orifice into the body of the brush toward the freeends of the bristles when the head is slid inward upon the tube. v

3. Ina brush, a discharge'tube adapted to lead from a reservoir, means for feeding the reservoir contents intothe tube to be expelled through the discharge end thereof, a brush head mounted upon the tube to move longitudinally whereby the discharge end of the tube may be carried from the brush base to and away from the free ends of the bristles of the brush, means for limiting the outward movement'of the brush upon the tube, and resilient means for forcing the brush head against such l miting means.

Ina brush, a tube, an extension sleeve having a closed upper end secured on the upper end of the tube and provided with- )ei'i )heral o eniii s a brush head formed with a sleeve surrounding the extension sleeve of the tube and normally. covering I the openings andprovided with astop pro- 1 into the interior of the tube 14 through the jection normally engaging the inner end of FRANK MCLAUGHLIN.
